Description

In order to support the spinal rod transverse connector of spinal fixation element
The present invention relates generally to the device that is used for spinal implant system, especially in the spinal rods profile prothesis along the connection on the length direction different parts of spinal column.The present invention more ad hoc relates to a kind of device that is used to be across between the rods, so that support the spinal fixation element of implant system, it is directly connected to rods on the vertebra.
Developed many method and systems, they are used for proofreading and correct and the stabilizing spine bending, and promote spinal fusion.In a system, be close to spinal column and longitudinally settled a flexible bar, by several retaining elements it be fixed to make progress different vertebraes along spinal column length on.Various retaining elements can be provided, and as hook or bone screw, they specifically are used to connect the specific portion of vertebra.Typically, with the assembly of two these class bars, on spinous process or sagittal each limit with one.
An example of this system is Danek Medical, the TSRH of Inc. Dorsal column system.In this system, with eyebolt hook or screw engagement on rods, they install on the rods slidably, and pin in the support of retaining element.A nut is spun on the threaded post of eyebolt, so that clamp support, and rigidly hook or screw element is fixed on the spinal fixation bar.The details of TSRH spinal implant system are at Danek Medical, and open in " surgical technic handbook " (nineteen ninety version) that Inc. provides, this publication enrolls in the reference material at this.
This TSRH
Figure 931202426_IMG3
A kind of structure of dorsal column system is seen shown in Figure 1.In this structure 10, a pair of flexible bar 11 and 12 spinal columns along patient extend at the either side of sagittal plane or spinous process S.In illustrated structure, bar 11 and 12 is close to lumbar vertebra, these bars are connected with 14 with second pair of bar 13,13 are connected patient's rumpbone with 14, bar 11 and 13 on the spinous process S left side, and bar 12 and 14 on the right can mesh with dull and stereotyped 15, they can be by picture Danek Medical, the CROSSLINK that Inc. makes Jam plate 803-101 or 804-043 constitute, and as TSRH Parts of system.
Several spinal fixation elements are fixed on the rods along the length direction of bar, and for example, vertebra hook 16 can be positioned in along some position on left bar or the right bar direction.These hooks are similar to TSRH The Danek base of a fruit hook 808-004 assembly of system.In addition, spinal fixation element can be a bone attachment screw 17, as the Danek vertebral screw of selling with production number 808-225.
It is found that in the postoperative stage, before spinal fusion takes place, between bar and the spinal fixation element great motion may take place, this motion may reduce the calibration result of spinal instrumentation 10.Therefore, at TSRH
Figure 931202426_IMG7
In the system, device provide pass card shape face laterally link bar, to form inflexible " tetrahedron " structure.These utensils can comprise a plate 18, as the CROSSLINK of Danek Medical company production
Figure 931202426_IMG8
Plate.This plate as in above-mentioned reference material " surgical technic handbook " describe more fully, its relative bar that interosculates rigidly is to reduce the correction loss that the whole time takes place.Direction along bar is connected on the bar by identical eyebolt combination 20 with 19 at the plate 18 that far-end connects, and said eyebolt assembly is used for spinal fixation element is connected to bar.
The surgeon is that spinal fixation element (hook and/or screw) is applied on the spinal column at suitable anatomy position with the purpose of this spinal implant system, then each retaining element is connected on the rods.In case spinal implant system is combined, it just can be proofreaied and correct the distortion of human body and make spinal stabilization.In the ideal case, retaining element is in and in fact is parallel on the sagittal plane S collinear position.But as a rule, discrete vertebra may depart from this collinear position, in the case, usually needs to do the profile reparation with the abnormal horizontal spinal curvature of pole pair (as scoliosis).Do the profile reparation by anatomical requirement with bar after, the vertebra that fixation hook or bone screw can be directly connected to lateral run-out gets on.
The spinal fixation system of technology in the past, particularly they being used for a difficulty on the rods is usually to have any problem in the transverse profile reparation that sagittal plane is made bar, particularly because bar also must delineate as profile normal cervical region and lumbar spine bending.The reparation of three-dimensional bar profile usually substantially is very difficult, and is impossible to a given patient on available space sometimes.
The undesired bending that requirement is regulated the spinal column for the treatment of with the profile reparation usually makes spinal fixation element have problems in the connection between bar and the particular vertebra, and this problem is difficult especially for bone screw.It is found that, from some interconnection bone screw is fixed on the vertebra normally preferred because it provides fixing on the vertebra base of a fruit of safety and has reduced danger to spinal canal.But, typical spinal rod system, TSRH for example shown in Figure 1
Figure 931202426_IMG9
System is not easy to adapt to the horizontal method that is connected with bone screw of this part between vertebra and vertebral column.And the base of a fruit that these systems are not easy to adapt to the variation that is provided on different vertebra planes enters angle.Another shortcoming of such system of system 10 is to need many different components to connect vertebras and cross the interconnected rigidly relative vertebra mast of sagittal plane as shown in Figure 1.
Therefore, requiring has a kind of system that more simplifies, and has the minimum parts of implantation individually, so that required time when not only will the minimizing system implanting, and reduces stimulation to patient's surrounding soft tissue.
And needing a kind of spinal fixation system, it is suitable for providing horizontal coupling easily between the multilamellar of spinal column or knotty rods.This system should be able to provide interosculating of this merogenesis, not can be used as the regiones vertebralis that bone is transplanted and do not disturb, to reach permanent fixing or make the vertebra fixation of damage motionless.
Also there is not at present such system that in these features each can be provided on a simple device known to the inventor.Also do not have a kind of known system to be suitable for being provided on the different spinal columns position with respect to rods spinal fixation element is installed, as spinal screw, it is selectively directed perhaps to allow retaining element to pass through some degree of freedom.The present invention is devoted to these needs, also provides simultaneously institute in the former spinal fixation system not have other benefit of discovery.
According to the present invention, provide a kind of, the device of the spinal rods of implanting across a pair of adjacent patient's vertebra along sagittal plane.Several spinal fixation elements connect along the length direction of bar, so that barre is fixed on the different vertebras.In one aspect of the invention, comprise that across the device between the bar device that is used for connecting rod reaches the device that connects spinal fixation element in the end of said device outside the connecting device of bar.In a specific embodiment, this device comprises one across the plate that an elongated central part is arranged between spinal rods, with the central part one be that bar is connected partly, it comprises that one normally has a bar elongated gap rectangle partly, accepts a bar by this slit and is connected with eye bolt.Rectangular bar connects bottom surface partly, can be into segmental so that rods is firmly located with respect to plate.

In order to promote understanding, also describe with special language with reference to the embodiment shown in the figure to inventive principle.Yet should be appreciated that this never means limits scope of the present invention, as to as illustrated in the further application of inventive principle because this may normally take place for the those skilled in the art relevant with the present invention.
According to one embodiment of the present of invention, Fig. 2 to Fig. 4 shows a lateral connector assembly 30.Assembly 30 comprises an elongated plate 32, and it is across between two rods 40, and their intersect the spinous process place on sagittal plane S of dashing forward.Plate 32 comprises central authorities across part 33, is combined into an integral body at its two ends and a pair of bar coupling part 35.Central authorities be decided by to stride across across partly length between the rods of spinous process S across distance, this distance is determined by human body.Central part 33 width are better to connect width partly less than bar, so plate 32 has a profile that has reduced being in close proximity to the spinous process place.Bar connects partly 35 and is connected at elbow 37 places of a pair of plate across part 33 with central authorities.Elbow 37 makes the angle side orientation of spinal fixation element with a best in order to connect the vertebra base of a fruit, will discuss in more detail at this.
Plate 32 also is included in away from central authorities across a retaining element connecting device or the part 41 that is threaded on each end of the bar connection part 35 of part 33.In other words, screw connection portion part is positioned at the outer end of plate 32.Each the screw connection portion part 41 that is constituted is in order to connect a spinal fixation element 43, and it is a spinal screw in illustrated preferred embodiment.But, should be appreciated that other spinal fixation element also can be used.In the present embodiment, spinal fixation element, or claim support 44 and a bone that spinal screw 43 comprises a top end opening to connect part 45, at this, screw 43 is made into to be similar to Danek Medical, the TSRH that Inc. provides

Opening head bone screw 808-225 to 475.Support 44 allows the plates 32 can " top load ", and just, lateral connector assembly 30 can be implanted on screw after screw is connected to vertebra.Similarly support can be inserted on other the spinal fixation element, for example the vertebra hook.Screw 43 is the TSRH from standard
Figure 931202426_IMG12
Bone screw is improved and is come, and makes it to comprise a surface 46 that is radial teeth groove, and its reason will do more complete explanation at this.
The bar on the plate 32 of touching upon in more detail connects partly 35, this some comprises a main body 50, and it is normally rectangular, and its width is greater than the width of central authorities across part 33, on each main body 50, designed a slit 51, and common long axis direction longitudinal extension along plate 32.The bottom of main body 50 has designed some fan-shaped 52, and it is in order to connect rods 40 by the method for knowing.For example, formed each radius of fan-shaped 52 is slightly smaller than the radius of rods 40 usually, so as can rods be placed in fan-shaped within.In illustrated embodiment, plate main body 50 comprise 5 this fan-shaped, 51 length direction separates equably along the slit for they so that regulate rods 40 with respect to lateral connector assembly 30, the diverse location of plate 32 particularly.These are fan-shaped for the spinal fixation bar provides device, so bar and plate can not move along the longitudinal axis of plate 32 between mutually.But, should be appreciated that the bottom of main body 50 can be slick, other device also can be used for making securely rods 40 fixing with respect to plate body 50 and slit 51.
Retaining element adapter or screw connection portion part 41 show in Fig. 2 and Fig. 4 in sufficient detail.As what described in the past, screw connection portion part 41 is placed in rod connecting device 39 ends of each side of plate 32.Partly 41 comprise a dististyle 55, and it outwards spreads into a common rectangle from main body 50.The end face 56 of each dististyle 55 comprises some radial teeth groove 57.Formed these teeth groove are used for being meshed with the teeth groove 46 of spinal fixation element 43.
Clearly illustrate more that at Fig. 4 radial teeth groove 57 is around annular orientation in one-tenth garden on the end face 56 of dististyle 55.Dististyle 55 also comprises an erection column 58, and it is protruding from the center of end face 56, and it comprises that mechanical whorl is with coupling nut 60.As shown in Figure 2, erection column 58 and nut 60 are used to clamp spinal fixation element 43, particularly the support between nut 60 and dististyle 53.Should be appreciated that radial alveolar surface 46 and 57 interaction can change the angle direction of spinal fixation element before being clamped by nut 60.The feature of this variable-angle makes certain part of spinal fixation element 43 and vertebra, and for example the base of a fruit provides bigger motility during engagement, particularly when bar curves complicated three-dimensional curve.Because this variable-angle feature, plate 32 can be directed best, so that for the feature on the fixing anatomy of avoiding influencing spinal column also will provide suitable adnexa to vertebra the time.
Lateral connector assembly 30 comprises rod connecting device 39, and it is used for that plate 32 is fixed to rods 40 and gets on.In a preferred embodiment, each rod connecting device 39 comprises an eyebolt 65, and its formed profile is so that put in the slit 51 of plate main body 50.Screw rod 66 protrudes from eyebolt 65 and passes slit 51 and mesh with nut 67.In the preferred embodiment, this eyebolt 65 and nut 67 can be similar in fact and be used for TSRH
Figure 931202426_IMG13
The TSRH of fixed system
Figure 931202426_IMG14
The eyebolt assembly, production number is 808-027 to 030, (by Danek Medical, Inc. provides).But, should be appreciated that any similar device may be used to being connected of bar 40 and plate main body 50, particularly within fan-shaped 52.In a preferred embodiment, fastening nut 60 pulls to plate main body 50 along erection column 58 with eyebolt, thus, be clamped in the bottom of eyebolt opening and plate main body 50 fan-shaped 52 between rods 40.
Lateral connector assembly 30 of the present invention provides important advantage when being used for the rods implant system.Particularly assembly 30 combines the connection of the rigid transverse between the rods with the device that is used to be connected the supraspinal spinal fixation element that is contained in spinal column, assembly 30 also provides the simple device that is used to produce a rectangle structure, and it can be owing to process is unclamped for a long time.
Important benefit is that the appearance by plate 32 provides, and its central authorities are across partly 33 having a less profile, when other of assembly are partly directed at an angle with respect to spinous process or sagittal plane S, so that provide some crosswise fixed to spinal fixation element.Bar connects partly 39 angle, the particularly angle of plate main body 50, and angle can pre-determine when making plate when the elbow 37 of their slave plates extends, so that regulate the aligning of some different retaining elements.For example, have been found that, with respect to the preferred crosswise fixed of sagittal plane S angle 70(Fig. 2 each successive lumbar vertebra) between 5 ° to 25 °.Like this, can provide several plates 32, wherein, fixed angles 70 changes when in the elbow 37 that is embodied in plate.
Plate 32 is the rustless steel or the similarly high-strength material manufacturing of handy medical grade, and preferably the material of plate has some pliabilities, helps curative effect because have been found that some pliability in the spinal fixation parts.In addition, a certain amount of flexible performance of plate 32 is convenient to have a spot of adjustment when it is shaped, particularly for the fixed angles 70 of spinal fixation element 43, when required by anatomy of spine.Have been found that in some example plate also must center on its longitudinal axis and do some distortion, so that regulate the feature of vertebra.But the effectiveness that is meshed at the alveolar surface 57 with on screw connection portion part 41 of the alveolar surface on the retaining element 43 46 is that this feature may be exempted the needs to the distortion of plate itself to the feature of a variable-angle fixedly is provided.
In an improvement, in central authorities across partly 33 and bar connects partly that the elbow 37 between 35 can be in also that bar connects partly and between the dististyle 41 that amplifies, so that provide a lateral angle for spinal fixation element.On the other hand, connecting partly at bar, arbitrary end of 35 can have two elbows.
